讲座题目：Overview of the University of Illinois and Research at the Illinois Center for Geological Sequestration of CO₂

讲座时间：2016年10月16日 上午10:00 -12:00
讲座地点：北二楼1401会议室
讲座人：Prof. Albert J. Valocchi

讲座内容：

    I will present an overview of research activities on geological sequestration of carbon dioxide, focusing on the Illinois Basin Decatur Project (IBDP) and Center for Geologic Storage of CO₂ (GSCO2). IBDP was a demonstration project for injection of 1 million tonnes of supercritical CO₂ into a deep saline sandstone reservoir. There was intensive post-injection monitoring using seismic methods and pressure sensors at observation wells. Small scale geological heterogeneity appeared to have a major control on reservoir-scale migration of the CO₂. GSCO2 is a new basic research center that builds on the knowledge and data from IBDP, focusing on predicting the migration of injected CO2 and identifying mechanisms of injection-induced micro-seismicity. One of the major science themes of GSCO2 is to use numerical models to improve understanding of the migration and storage of CO₂ at a variety of spatial and temporal scales. I will give an overview of the modeling activities in the center, focusing on pore-scale simulation using pore-network and lattice Boltzmann models. I will also present some background information about the Department of Civil and Environmental Engineering and the University of Illinois.
